[Discuss-gnuradio] how to suspend the flowgragh without any signal transmission for a few sec

[Yan Nie]

Dear all,

how to pause the system for 5 milliseconds? I'm trying to transmit signal then 
suspend the system without any signal transmission for about 5 milliseconds. 
The following is the part of code that I use to implement this, but it just 
continuously transmitting signal, and I cannot see any no signal transmission 
part on oscilloscope.


payload_13bit = '\x01\x01\x01\x01\x01\x0'
while(start_flag ==  1)
           msg_13bit = gr.message_from_string(payload_13bit)
           top_block._ls_msgq.insert_tail(msg_13bit)
           time.sleep(0.005)


Could you please help to see what the problem here? Why it cannot stop the 
transmission for 5 milliseconds.


Really appreciate your help.


Thanks,
Yan
